#Python导入数据-分析师项目Alex

Question

我正在研究Python分析组合，看分析师Alex的视频。(https://www.youtube.com/watch?v=ocdwh0KYeUs&list=PLUaB-1hjhk8H48Pj32z4GZgGWyylqv85f&index=5)

然而，他提供的代码在任何时候都不起作用。我尝试了这个代码$exportXDG_RUNTIME_DIR=“”(在：Jupyter notebook permission error中找到)，但这也不起作用。

import pandas as pd 
import numpy as np 
import seaborn as sns 
import matplotlib.pyplot as plt 
import matplotlib.mlab as mlab 
import matplotlib 
plt.style.use('ggplot') 
from matplotlib.pyplot import figure 
%matplotlib inline 
matplotlib.rcParams['figure.figsize'] = (12,8) 
pd.options.mode.chained_assignment = None 
df = pd.read_csv(r'C:\Users\enana\Downloads\movies.csv')

当我做这个项目的时候，我只是试着跟着做，所以我真的不明白上面发生了什么。当我返回如下代码时，我不知道发生了什么：

请帮帮忙。

请尝试以下几点:在处理这样的问题时，我们需要理解我们所提供的路径，它应该是双"\“。

df = pd.read_csv(r"C:\\Users\\enana\\Downloads\\movies.csv")

你的问题可能会解决。
